COMPRESSOR START UP CONTROL SHUTDOWN INTERFACE STRATEGY This document is issued and administered by the Air Liquide Engineering Standards Department Paper copies of this document are considered to be uncontrolled and users should always check for the most recent revision READY TO START The Ready to Start of CO compressor is configured in compressor PLC Common Trip status of 2 out of 3 loops is sent from SGS to PLC which is taken into account for ready to start START UP The CO compressor could be started either From Compressor remote panel From site local push button panel Then the Start command is sent to electrical room via SGS Running feedback from electrical room is sent to SGS to check discrepancy between ON command and Status of the motor This information is then sent to PLC Power consumption is directly sent from electrical room to PLC NORMAL OPERATION 1stStage Suction pressure Vaporisation pressure of liquid CO in thermo siphon is adjusted by 1ststage suction pressure If the pressure is higher then corresponding temperature in Cold box is higher and would affect cold balance CO recovery For stable operation of the Cold Box it is necessary to maintain stable compressor 1st 2ndstage suction pressures DCS will control this pressure via PIC 11482 1ststage suction pressure and will send an output to PLC PLC will send signal via a low selector to inlet guide vanes on site 2ndStage Suction pressure CO CH4 column pressure is adjusted by 2ndstage suction pressure If the pressure is higher then corresponding heat duty reboiler duty required to produce CO is higher For stable operation of the Cold Box it is necessary to maintain stable compressor 2ndstage suction pressures DCS will control this pressure via PIC 16706A 2ndstage suction pressure and will send an output to PLC PLC will send signal via a low selector to inlet guide vanes on site SHUTDOWN The trip conditions are separated into 2 categories Safety Trip Conditions These trip conditions are generated as a result of 2 out of 3 voting logic and are configured in SGS system These signals are transferred to PLC via DCS Following are the loops configured in this category PT 11616 1stStage Suction pressure PT 11626 2ndStage Suction pressure 法国液空集团 项目名称万华 51 3461 00项目编号 CO压缩机启动 控制及关闭方法 准备开始 命令配置在一氧化碳压缩机的PLC 公共的旅程状态3选2 环路从SGS发送到PLC 这是准备开始的信号 基于PLC的控制系 统 启动 CO压缩机启动的两种途径 从远程控制面板启动 现场启动 现场按钮 然后 开始 命令通过SGS发送到电气室 通过检查启动信号和电机状态从而返回信 号 该信号通过电器运行室反馈到SGS 然后将此信息发送到PLC 电力直接从电气室发送到PLC 常规操作 热对流系统中CO液体的汽化压力受一级吸入压力的影响 如果压力 变高 相应的冷箱的温度会升高 从而影响冷平衡和CO回收 为了保证冷箱的稳定 有必要确保压缩机一级和二级吸入压力稳 定 DCS系统通过压力表 一级吸入压力 来控制 它会输出信号 给PLC PLC通过发送信号给低速控制器来调节现场的阀门开度 关机 路径条件分成两类 安全路径条件 这些路径条件通过2选3逻辑产生并在SGS系统中得 到确认 这些信号通过DCS传给PLC 以下是此类 的循环配置 压力表11616 一级吸入压力 压力表11626 二级吸入压力 CO CH4柱压力通过二级吸气压力调节 如果压力升高 产生 CO所需的相应热负荷也提高 为了保证冷箱的稳定 有必要确 保压缩机二级吸入压力稳定 DCS系统通过压力表 一级吸入 压力 来控制 它会输出信号给PLC PLC通过发送信号给低速 控制器来调节现场的阀门开度 本文档是由液化空气公司工程标准部门发布和管理的 纸本文件的复印件是可变的 用户应该始终检查最新的修订 PROJECT NAME WANHUA PROJECT NUMBER 51 3461 00 Doc No C 013
